What I did was just walk up to the counter, stare at her with big eyes and say "You are the prettiest girl I have seen....I like you very much"....
I tell you, the woman blushed and smile so sweetly at me, I really made her day. After that, everytime she see me, she would smile and look my way wherever I sit.
I didn't make any move after that, otherwise sure I score goal.
Women just love a man with guts
